Planning for retirement can feel complicated, but Ramit Sethi’s retirement calculator from I Will Teach You to Be Rich is designed to make it simple.

It doesn’t rely on Wall Street–level simulations. Instead, it gives you a clear, actionable estimate of how much you need and whether you’re on track.

What Ramit Sethi’s Retirement Actually Does

The calculator asks for a few key pieces of information:

  • Current savings
  • Monthly or annual contributions
  • Expected retirement age
  • Life expectancy
  • Desired annual spending in retirement

Then it answers two main questions:

  1. How much money will you have by retirement
  2. How much will you need to sustain your lifestyle

It compares these numbers to show whether you’re ahead, on track, or need to save more.

The 4% Rule
  • You can safely withdraw about 4% of your retirement portfolio each year.
  • Withdrawals are adjusted for inflation over time.
  • The strategy is designed to last roughly 30 years.
Example: $1,000,000 portfolio → $40,000 per year income
Required Savings = Annual Spending ÷ 0.04
$100,000 ÷ 0.04 = $2,500,000 needed
This rule is based on research by Bill Bengen and forms the foundation of many retirement calculators.

How Your Retirement Number is Calculated

  • 1
    Estimate your future lifestyle by entering your expected annual spending in retirement, often assuming a lifestyle similar to today.
  • 2
    Apply the 4% rule to convert spending into the total savings required.
    Example: Example: $120,000/year → $3,000,000 target
  • 3
    Estimate retirement duration, typically around 30 years based on average life expectancy.
  • 4
    Compare with your savings trajectory. The calculator factors in:
    • Current savings
    • Monthly contributions
    • Expected investment growth
  • 5
    Project total savings at retirement and determine whether it meets your target amount.

Investment Growth Assumptions

Sethi’s calculator assumes long-term market growth, typically around 7–8% annually after inflation adjustments.
Future Value = Current Savings × (1 + r)years + Monthly Contributions Growth
r represents the assumed annual rate of return.

Limitations of Ramit Sethi’s Retirement Calculator

The calculator is helpful, but it has some constraints.

  • Precision is limited. Assumes fixed returns and a 30-year retirement and does not model market volatility.
  • Uses US-focused assumptions for life expectancy, retirement systems, and income sources.
  • Does not fully account for taxes, healthcare shocks, or sequence-of-return risk.

It’s simple by design: not perfect, but highly actionable, helping you see if you’re on track and what steps to take next.
